- Various display devices such as liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays include a display panel which includes a pixel region. High surface quality of the pixel region of the display panel is desired in all industries. To improve the surface quality of the pixel region, it is important to prevent the display panel from being damaged during the manufacture of a display device and after the completion of the display device.
- One way of preventing the display panel from being damaged during the process of manufacturing the display device is to perform the process of manufacturing the display device after a protective film is placed on the surface of the display panel. The protective film placed on the surface of the display panel absorbs shocks that can be applied to the display panel during the process of manufacturing the display panel. Thus, the protective film may be damaged instead of the display panel.
- On occasion, after a top chassis is coupled to the display panel, it is not easy to remove the protective film since a base plate of the top chassis is placed on edges of the protective film. Therefore, the protective film is removed before the top chassis is coupled to the display panel, and another protective film is attached onto the top chassis after the completion of the display device in order to prevent the damage of the display panel. The protective film can be arbitrarily removed by a consumer.
- Aspects of the present invention provide a display device which is structured to allow a protective film to be removed easily.
- Aspects of the present invention also provide a top chassis for a display device, which is structured to allow a protective film to be removed easily.

Thetop chassis 100 is on the edges of thedisplay panel 200, that is, the non-pixel region and side surfaces of themid frame 400. Thebase plate 130 of thetop chassis 100 defines the firstopen surface 110 which exposes the pixel region and the secondopen surface 120 which protrudes from an end of the firstopen surface 110. In the current embodiment, the firstopen surface 110 is shaped like a rectangle, and an end of the firstopen surface 110 is a vertex of the rectangle. In addition, the secondopen surface 120 extends from theopen surface 110 with a uniform width. In the current embodiment, the secondopen surface 120 not only exposes the whole of an end of theprotective film 900 which faces the secondopen surface 120 but also extends further in a direction in which it protrudes from the firstopen surface 110. - The
display device 1000 may further include thefilm detaching member 910. Thefilm detaching member 910 may be attached to theprotective film 900 and may be at least partially exposed through the secondopen surface 120. - Specifically, the
film detaching member 910 may include an adheringportion 911 and a protrudingportion 912. The adheringportion 911 of thefilm detaching member 910 may be attached to an end of theprotective film 900. Here, the adheringportion 911 may be attached onto theprotective film 900 which faces the secondopen surface 120. Anadhesive layer 960 may be formed between the adheringportion 911 of thefilm detaching member 910 and theprotective film 900. The protrudingportion 912 of thefilm detaching member 910 may extend from the adheringportion 911 in the direction in which the secondopen surface 120 protrudes. In addition, the protrudingportion 912 may extend upward from an end of the adheringportion 911 to contact thebase plate 130 of thetop chassis 100. Here, the protrudingportion 912 and the adheringportion 911 may form an obtuse angle.

display device 1000 according to the current embodiment includes the secondopen surface 120 defined by thetop chassis 100, thefilm detaching member 910 attached to an end of theprotective film 900 is exposed, and theprotective film 900 can be easily removed using the protrudingportion 912 of thefilm detaching member 910. That is, theprotective film 900 used to prevent thedisplay panel 200 from being damaged during the process of manufacturing thedisplay device 1000 does not need to be removed before thetop chassis 100 and thedisplay panel 200 are coupled to each other. Instead, theprotective film 900 can be arbitrarily removed by a consumer after the completion of thedisplay device 1000. Therefore, a process of removing theprotective film 900 during the manufacture of thedisplay device 1000 and a process of attaching anotherprotective film 900 onto thetop chassis 100 after the completion of thedisplay device 1000 can be omitted. Accordingly, this can reduce the time required to manufacture thedisplay device 1000. Furthermore, since it is not necessary to attach anotherprotective film 900 onto thetop chassis 100, the material cost of thedisplay device 1000 can be saved. -
